Patent number: 11809070Abstract: A switchable projector module includes a holder, a projector, and a switchable diffuser. The holder includes a first connection tank and a second connection tank, in which the second connection tank is located at a side of the first connection tank. The second connection tank has a spilling glue trench. The projector is engaged with the first connection tank and is configured to project a pattern image onto the second connection tank. The switchable diffuser is engaged with the second connection tank. The switchable diffuser is configured to switch between a first mode and a second mode, so as not to diffuse the pattern image in the first mode and diffuse the pattern image in the second mode.Type: GrantFiled: August 21, 2022Date of Patent: November 7, 2023Assignee: HIMAX TECHNOLOGIES LIMITEDInventors: Han Yi Kuo, Yin Tung Lu, Shi Jen Wu

Patent number: 11590688Abstract: An imprinting apparatus includes an imprinting platform, an imprinting roller, a transfer module and a lifting and pressing mechanism. The imprinting roller is disposed above the imprinting platform. The transfer module includes a transfer film, wherein the transfer film is located between the imprinting roller and the imprinting platform. The lifting and pressing mechanism is linked with the imprinting roller, wherein the lifting and pressing mechanism drives the imprinting roller to move along a normal direction of the imprinting platform and selectively pressurizes the imprinting roller.Type: GrantFiled: August 29, 2021Date of Patent: February 28, 2023Assignee: HIMAX TECHNOLOGIES LIMITEDInventors: Ruei Yu Weng, Han-Yi Kuo, Yin-Tung Lu, Jui Pin Tsai

Patent number: 11531267Abstract: An imprinting apparatus includes an imprinting platform having a first side and a second side opposite to each other, an imprinting roller disposed above the imprinting platform, a transfer module, and a film separation module. The transfer module includes a transfer film located between the imprinting roller and the imprinting platform and a fixed frame fixed beside the first side of the imprinting platform and a movable frame disposed on the second side of the imprinting platform that clamp opposite sides of the transfer film. The movable frame is adapted to move horizontally relative to the fixed frame to change a flatness of the transfer film. The film separation module is connected to the movable frame, and is adapted to drive the movable frame to be turned from a first position to a second position, such that a rounded corner is formed between the transfer film and the imprinting roller.Type: GrantFiled: May 20, 2021Date of Patent: December 20, 2022Assignee: HIMAX TECHNOLOGIES LIMITEDInventors: Ruei Yu Weng, Chung-Ho Tseng, Han-Yi Kuo, Yin-Tung Lu, Jui Pin Tsai
